Wireless Telnet Disconnects and Response Time is Slow

Using Intermec CK61 with TE200 terminal emulation and wireless is showing 500 ms avg with 1 timeout every 5 pings, getting -72 dBi signal and disconnects in some dead spots. Slow response and disconnects from Seattle Labs telnet server which is on SAP Console across T1 network then connects to SAP server. Access Points are mounted upside down on 50 foot ceiling above warehouse with high rack paper storage, if there is about 40 feet of solid paper line of sight to AP there is no signal. Thinking of adding more access points, they appear to be regular 2 or 3 dBi omni directional APs, I've read that for high rack storage usually directional antennas are used every 4 rows. We may replace entire wireless network controller and APs are old.

With the Intermec CK61 and our wireless we had setup a wireless network name for them and changed it to only use 1 slowest b/g setting which stopped the CK61 from roaming so much it slowed it down, we put in recommended Intermec patches like one to increase signal strength it checks for before roaming also but our signal here was so low in places they still roamed, had dead spots. We needed several more access points because of all the high rack storage of paper absorbing the 802.11 signals, best to put a directional AP at end of each aisle if they are long aisles.

it could be difficult to answer; sincerely i cannot understand entirely your request, due to my limited comprehension of american english.
i think you should buy one new ap and then test the coverage you could reach, positioning it in several places; the signal has be not les then 60 db, if you don't want headheaches no more. test and plan your new network.
when the test are done, buy the aps you need, and buy one or two more aps to have some to replace the broken in the future.
the aps have to be connected to the network via lan cable, instead of via radio, because of the stability of the signal.
a characteristic you should search for in your aps, is the function called roaming: it permits you to route from one ap to another, without loss of signal, when in mobility.
